Abstract

Abstract: This case report was aimed to evaluate the clinical aesthetic effect of immediate implant without flap and autocrown restoration for traumatic teeth in the aesthetic area of anterior teeth assisted by digital guide plate, and explore the clinical factors affecting implant restoration in the aesthetic area. After minimally invasive extraction of the affected tooth due to traumatic root fracture of the patient's left upper central incisor, immediate implantation without flap was performed under the assistance of digital guide plate, and immediate temporary restoration was performed with autogenous crown at the same time. Six months later, personalized mold extraction column was prepared for precise mold extraction, and personalized all-porcelain abutment-zirconia all-porcelain crown restoration was finally completed. During the 18-month follow-up period, the patient achieved a good red-white aesthetic effect, and imaging examination also showed good peri-implant bone bonding and no absorption at the edge bone level. This case showed that with the assistance of digital guide plate, immediate implantation of traumatic teeth in aesthetic area without flap and immediate autologous crown restoration can achieve good red-white aesthetic effect.
